What are the advantages of motor operated valves over pneumatic valves?

Good question Usually motor operated valve used in big pipe lines sizes which it is need strong torque and for ON/OFF condition not to control the process, We can use rather than M.O.V pneumatic ON/OFF valve with piston actuator (Double Acting) but in this case the accessories it will cost you more because you need to provide pneumatic amplifier and big actuator depend on the pipe size. That is why better to use M.O.V the motor will rotate the gears and the gears will rotate the valve with low cost. Contact me for more clarification if there is.


What is the function of pneumatic valves?

If you are talking about a pneumatic solenoid valve the function of it is to control the air in and out flow in a pneumatic actuator.


What is the definition of pneumatic valve?

A valve which requires pressurised air to operate (open or close) is known as pneumatic valve. A valve has a valve base through which the media (could be be air, liquid, steam, gas...) flows and a actuator mounted on the base which helps operate the valve. This actuator could be of pneumatic type. (or elctrically operated motorised type)


What difference between mov and zv valve?

A MOV (motor operated valve) is a type of valve that is controlled by an electric motor, while a ZV (zone valve) is a valve that controls the flow of water or steam in heating and cooling systems in residential and commercial buildings. The main difference is in their application and operation, with MOVs being used for larger industrial processes and ZVs used for HVAC systems in buildings.

What is the differences of direct acting actuator and reverse acting actuator?

When a pressure signal is applied, the valve shaft moves in the direction opposite that of the direct-acting actuator, but it follows the same operating principle. In the reverse-acting actuator, the valve shaft is pulled into the actuator by the application of a pressure control signal.
